Acts 16:10

7 and when they were come over against Mysia, they assayed to go into Bithynia; and the Spirit of Jesus suffered them not;

8 and passing by Mysia, they came down to Troas.

9 And a vision appeared to Paul in the night: There was a man of Macedonia standing, beseeching him, and saying, Come over into Macedonia, and help us.

10 And when he had seen the vision, straightway we sought to go forth into Macedonia, concluding that God had called us to preach the gospel to them.

11 Setting sail therefore from Troas, we made a straight course to Samothrace, and the day following to Neapolis;

12 and from thence to Philippi, which is a city of Macedonia, the first of the district, a [Roman] colony: and we were in this city tarrying certain days.

13 And on the sabbath day we went forth without the gate by a river side, where we supposed there was a place of prayer; and we sat down, and spake unto the women that were come together.
